The Gyrojet from "You Only Live Twice".
Walther Wa2000 from "Living Daylights". A weapon I still lust after.
In one of his final columns, Jeff Cooper presented what he felt would be the next great marksmanship challenge which was 20 rounds in a 20" circle at 1000 yards in 60 seconds or less. I've always felt that would be the weapon in the hands of the person who did it.
Sexy for sure but if you had to ask what it cost you couldn’t afford it. A more functional long range weapon could be put together for just under a grand starting with the Savage heavy barreled rifle in one of the WSM calibers; I’d view the 270 WSM as the most interesting of those.
